Gentleness is the ability to bear reproaches and slights with moderation, and not to embark on revenge quickly, and not to be easily provoked to anger, but be free from bitterness and contentiousness, having tranquility and stability in the spirit.
We can more easily avenge an injury than requite a kindness; on this account, because there is less difficulty in getting the better of the wicked than in making one's self equal with the good.
For one thing is needful: that a human being should attain satisfaction with himself, whether it be by means of this or that poetry or art; only then is a human being at all tolerable to behold. Whoever is dissatisfied with himself is constantly ready for revenge, and we others will be his victims, if only by having to endure his ugly sight.
My revenge is fraternity! No more frontiers! The Rhine for everyone! Let us be the same Republic, let us be the United States of Europe, let us be the continental federation, let us be European liberty, let us be universal peace!
I'm a fighter. I believe in the eye-for-an-eye business. I'm no cheek turner. I got no respect for a man who won't hit back. You kill my dog, you better hide your cat.
Of ill-temper there are three kinds: irascibility, bitterness, sullenness. It belongs to the ill-tempered man to be unable to bear either small slights or defeats but to be given to retaliation and revenge, and easily moved to anger by any chance deed or word. Ill-temper is accompanied by excitability of character, instability, bitter speech, and liability to take offence at trifles and to feel these feelings quickly and on slight occasions.
